Tuning Machine Adjustments
Over time, tuners can become loose. Get in the habit of checking the tension with every string change. If you notice a change in the tension of a tuner, use a small flathead or Phillips screwdriver to tighten it (turn clockwise) or loosen it (turn counterclockwise) accordingly. Warning: While the screw should be snug, do not overtighten, as you may strip the screw.
